Shared network-interface controller (NIC) using advanced switching (AS) turn-pool routing field to select from among multiple contexts for multiple processors

摘要: A network connection is transparently shared among two or more processors. interface controller (NIC) has sets of context registers that may include Ethernet command and pointer registers. Each set accessed by a different processor. The processors are separated from the NIC an Advanced Switching (AS) network. AS packets to write embedded in contain turnpool information specifies route through Turnpools for unique used indicate which access. turnpool-identified assigned external (Ethernet) address. External received sent inside over correct processor associating packet's address with turnpool-context.
